[0039] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0040] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0041] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning as understood by a person with ordinary skills in the field to which this application pertains.

[0042] In the description of the embodiments of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] The inventors of this application have discovered that after a distillation separation device has been running in a hot chamber for a long time, some components of the distillation separation device are prone to damage. However, due to the inconvenience of assembly and disassembly in related technologies, it is difficult to repair or replace the vulnerable parts, which makes it difficult for the distillation separation device to operate stably in the hot chamber for a long time and results in a short service life.

[0044] Therefore, in order to solve the above-mentioned technical problems, the embodiments of this application provide a distillation separation device that is easy to assemble and disassemble in a hot chamber, which is used to separate the target component from the material to be separated.

[0045] like Figure 1 and Figure 2 As shown, Figure 1This is a schematic diagram of a distillation separation apparatus according to an embodiment of this application; Figure 2 This is a cross-sectional schematic diagram of a distillation separation apparatus according to an embodiment of this application. The distillation separation apparatus provided in the embodiment of this application may include a furnace body assembly 10 and a distillation collection member 20. The furnace body assembly 10 may include a shell 11 and a furnace body 12. The furnace body 12 may include a main furnace body section 121 and an auxiliary furnace body section 122. The main furnace body section 121 is spliced ​​above the auxiliary furnace body section 122, and the main furnace body section 121 forms a heating and heat preservation chamber 1210. The auxiliary furnace body section 122 is connected to the shell 11, and the shell 11 can enter the heating and heat preservation chamber 1210 of the main furnace body section 121. The distillation collection member 20 is detachably connected to the shell 11, and the target component evaporates in the distillation collection member 20, separates from the material to be separated, and condenses to form a solid.

[0046] The distillation separation device provided in the embodiments of this application splices the main furnace body section 121 and the auxiliary furnace body section 122, and sets the distillation collection component 20 to the shell 11 in a detachable manner, so as to facilitate the assembly and disassembly of the distillation separation device in the hot chamber, thereby facilitating the maintenance of the distillation separation device, and thus ensuring that the distillation separation device can operate stably in the hot chamber for a long time and extending its service life.

[0047] In the embodiments of this application, splicing two components means that one component is placed or stacked on top of another component and supported by the other component. The component on top can move vertically upward under the action of external force to separate from the component below. In some embodiments, the two spliced ​​components can be positioned by respectively providing positioning holes and positioning pins extending vertically; or by respectively providing grooves or protrusions extending vertically.

[0048] In some embodiments, the material to be separated may be raw material powder formed after spent fuel electrolytic refining; the target component may be molten salt remaining in the spent fuel electrolytic refining material to be separated.

[0049] In some embodiments, the furnace body assembly 10 may further include a first lifting member 101 and a second lifting member. The first lifting member 101 and the second lifting member are respectively disposed on the main furnace body section 121 and the auxiliary furnace body section 122, so that the main furnace body section 121 and the auxiliary furnace body section 122 can be lifted by lifting equipment, thereby disassembling and assembling the furnace body assembly 10, so as to remove the main furnace body section 121 and the auxiliary furnace body section 122 from the hot chamber for maintenance.

[0050] like Figure 3 and Figure 4 As shown, Figure 3 This is a cross-sectional schematic diagram of the main structure of a distillation separation apparatus according to an embodiment of this application, wherein the collecting element does not seal the opening at the bottom of the shell; Figure 4 This is a cross-sectional schematic diagram of the main structure of a distillation separation apparatus according to an embodiment of this application, wherein the collecting member seals the opening at the bottom of the shell. In some embodiments, the main furnace body section 121 may include a furnace cover body 1211 and a first furnace body section 1212. The furnace cover body 1211 and the first furnace body section 1212 are detachably connected. The furnace cover body 1211 and the first furnace body section 1212 together form a heating and insulation chamber 1210. A first lifting member 101 is formed in the first furnace body section 1212. Since the furnace cover body 1211 and the first furnace body section 1212 are spliced ​​together, it is convenient to assemble and disassemble the main furnace body section 121 in the hot chamber, and it is convenient to perform segmented maintenance, thus improving the convenience of maintenance. In such an embodiment, the first furnace body section 1212 has a top opening, and the furnace cover body 1211 closes the top opening of the first furnace body section 1212.

[0051] In some embodiments, the furnace body assembly may further include a cover lifting member 102. The cover lifting member 102 is disposed on the furnace cover 1211 so that the furnace cover 1211 can be lifted by means of a lifting device, thereby facilitating the assembly and disassembly of the main furnace body section 121.

[0052] In some embodiments, the first furnace body segment 1212 may include a plurality of first positioning members 104 arranged along the top opening of the first furnace body segment 1212 for positioning the furnace cover 1211 so that the furnace cover 1211 is aligned with the top opening of the first furnace body segment 1212, thereby facilitating the hoisting of the furnace cover 1211 to the top opening of the first furnace body segment 1212 and splicing it with the first furnace body segment 1212.

[0053] In some embodiments, the surface of the first positioning member 104 facing the furnace cover 1211 is inclined to guide the furnace cover 1211 during the process of hoisting the furnace cover 1211 to the first furnace body section 1212.

[0054] In some embodiments, the furnace body assembly 10 may further include a main heating element 13. The main heating element 13 is used to heat the shell 11 so that the target component can evaporate in the distillation collection element 20. The main heating element 13 is connected to the furnace cover body 1211 and extends downward from the furnace cover body 1211 into the heating and insulation chamber 1210. Since the main heating element 13 is connected to the furnace cover body 1211 and extends downward from the furnace cover body 1211 into the heating and insulation chamber 1210, when the main heating element 13 needs maintenance, the main heating element 13 and the furnace cover body 1211 can be lifted upward together using hoisting equipment, separated from the first furnace body section 1212, and then lifted out of the hot chamber, thereby facilitating the maintenance of the main heating element 13.

[0055] In some embodiments, the main heating element 13 may include a plurality of heating sections 131 arranged in an annular structure, and the housing 11 can enter the annular structure. This arrangement enables uniform heating of the portion of the housing 11 entering the annular structure, ensuring that the target component can be fully evaporated.

[0056] In some embodiments, the furnace cover body 1211 may include a furnace cover shell 12111 and a top insulation layer 12112 disposed within the furnace cover shell 12111. In some embodiments, a cover hanger 102 is disposed on the upper surface of the furnace cover shell 12111.

[0057] In some embodiments, each heating segment 131 may have a U-shaped structure, with the openings of the U-shaped structure of each heating segment 131 extending to both ends and passing through the top insulation layer 12112 to connect with the furnace cover shell 12111, thereby securely mounting the heating segment 131 to the furnace cover body 1211. These U-shaped heating segments 131 may be arranged at equal intervals around a circumference concentric with the shell 11 to facilitate uniform heating of the shell 11. In some embodiments, the heating segments 131 of the main heating element 13 may be arranged in parallel.

[0058] The first furnace body section 1212 may include a first furnace shell 12121 and a first annular heat insulation member 12122 disposed inside the first furnace shell 12121. The first annular heat insulation member 12122 forms a cavity with a top opening. The top heat insulation layer 12112 closes the top opening of the cavity to form a heating and heat insulation cavity 1210 together with the first annular heat insulation member 12122. This effectively reduces heat loss while facilitating disassembly and assembly, and ensures the heat insulation effect inside the heating and heat insulation cavity 1210.

[0059] In some embodiments, the first furnace body segment 1212 may include a support plate 12126 connected to the lower end of the first furnace outer shell 12121 and disposed below the first annular heat insulation member 12122. The support plate 12126 is used to support the first annular heat insulation member 12122. Since the first annular heat insulation member 12122 is not typically made of a rigid material, the support plate 12126 can provide support for the first annular heat insulation member 12122.

[0060] In some embodiments, the first lifting member 101 is disposed on the first furnace shell 12121.

[0061] In some embodiments, an opening is formed at the bottom of the furnace cover shell 12111, and the furnace cover body 1211 may further include a furnace cover splicing fitting 12113 disposed at the opening of the furnace cover shell 12111. An opening is formed at the top of the first furnace cover 12121, and the first furnace body segment 1212 may include a body splicing fitting 12125 disposed at the opening of the first furnace cover 12121. The body splicing fitting 12125 faces the furnace cover splicing fitting 12113 to facilitate splicing of the furnace cover body 1211 and the first furnace body segment 1212.

[0062] In some embodiments, the furnace cover splicing fitting 12113 and the body splicing fitting 12125 have flange structures to increase the contact area, facilitate the placement of the furnace cover body 1211 on the first furnace body section 1212 for splicing with the first furnace body section 1212, and improve stability.

[0063] In some embodiments, the body splicing fitting 12125 forms a body positioning member, and the furnace cover splicing fitting 12113 correspondingly forms a furnace cover positioning hole. When the furnace cover body 1211 is hoisted onto the furnace body 12, the body positioning member can enter the furnace cover positioning hole to circumferentially position the furnace cover body 1211 and the furnace body 12, thereby preventing relative circumferential rotation between the two. In some embodiments, the body positioning member can be a positioning post fixed to the body splicing fitting 12125.

[0064] In some embodiments, the first annular insulation member 12122 is connected to the first furnace shell 12121 for joint lifting. When it is necessary to repair the first annular insulation member 12122 or clean the inside of the heating and insulation cavity 1210, the first annular insulation member 12122 and the first furnace shell 12121 can be lifted off together.

[0065] In some embodiments, the first furnace body section 1212 may further include a first water-cooled cavity 12124. The first water-cooled cavity 12124 is formed in the first furnace shell 12121 and is used to cool the first furnace shell 12121 to reduce the temperature of the outer surface of the first furnace shell 12121.

[0066] In some embodiments, the additional furnace body section 122 may include a second furnace shell 1221 and a second annular heat insulation member 1222 disposed radially inside the second furnace shell 1221. The second annular heat insulation member 1222 is used to reduce heat loss and ensure the heat insulation effect of the additional furnace body section 122. In some embodiments, the additional furnace body section 122 may also include a second water-cooled cavity 1223. The second water-cooled cavity 1223 is formed in the second furnace shell 1221 and is used to cool the second furnace shell 1221 to reduce the temperature of the outer surface of the second furnace shell 1221.

[0067] In some embodiments, the first furnace shell 12121 and the second furnace shell 1221 can be cylindrical components that extend vertically through the furnace.

[0068] In some embodiments, the first annular insulation member 12122 and the second annular insulation member 1222 can be aluminum silicate boards.

[0069] In some embodiments, the second furnace body section further includes a second connecting portion 1224 formed on the upper part of the second furnace shell, the second connecting portion 1224 cooperating with the support plate 12126. The second connecting portion 1224 may have a flange structure with mounting holes, and the support plate 12126 and the second connecting portion 1224 are detachably connected by bolts.

[0070] In some embodiments, the distillation collection unit 20 may include a collection unit 22. The collection unit 22 is configured to collect the condensed target component and is detachably connected to the housing 11 below the furnace body 12. The furnace body assembly 10 may also include an auxiliary heating element 14. The auxiliary heating element 14 heats the housing 11 to melt the target component that has not condensed in the collection unit 22 and allow it to flow into the collection unit 22 under gravity, thereby preventing the target component from remaining and accumulating outside the collection unit 22 and ensuring that the target component is fully collected by the collection unit 22. Simultaneously, because the collection unit 22 is located below the furnace body 12 and outside the furnace body 12, the heating and insulation chamber 1210 has minimal impact on the temperature of the lower part of the housing 11 and the collection unit 22, resulting in lower temperatures in the lower part of the housing 11 and the collection unit 22, which is conducive to condensation. Furthermore, this configuration allows the inherent atmosphere within the heating chamber to cool the collection unit 22, which is beneficial for the collection unit 22 to condense the target component and improves the condensation effect.

[0071] In some embodiments, the auxiliary heating element 14 is disposed on the auxiliary furnace body section 122. When the auxiliary heating element 14 needs to be repaired, the main furnace body section 121 can be lifted off using the first lifting member 101, and then the auxiliary heating element 14 and the auxiliary furnace body section 122 can be lifted off together using the second lifting member, thereby facilitating the repair of the auxiliary heating element 14.

[0072] See Figure 6 In some embodiments, the auxiliary heating element 14 may be connected to the second furnace shell 1221. Specifically, the auxiliary heating element 14 may be connected to the second furnace shell 1221 through the second annular insulation element 1222. In some embodiments, the auxiliary heating element 14 may be formed by a tortuous electric heating wire that forms an annular structure around the shell 11 to facilitate uniform heating of the shell 11.

[0073] In some embodiments, the main heating element 13 is disposed radially outward of the housing 11. The auxiliary heating element 14 is disposed radially outward of the housing 11 and located below the main heating element 13. The first annular heat-insulating element 12122 is located between the auxiliary heating element 14 and the main heating element 13.

[0074] See Figure 8 and Figure 9 , Figure 8 This is a schematic cross-sectional view of the fit between the shell and the distillation collection member 20 according to an embodiment of this application; Figure 9 This is a schematic cross-sectional view of a distillation collection unit 20 according to one embodiment of this application. In some embodiments, the distillation collection unit 20 may further include a distillation unit 21. The distillation unit 21 may be joined with the collection unit 22.

[0075] The distillation element 21 is used to load the material to be separated and is configured to enter the interior of the shell 11. After the target component evaporates in the distillation element 21, it enters the shell 11 and then enters the collection element 22 to condense and form a solid. The main heating element 13 is used to heat the distillation element 21 so that the target component in the distillation element 21 can be evaporated by heat.

[0076] In some embodiments, the distillation collector 20 may further include a transition member. The transition member is disposed between the distillation member 21 and the collector 22. The transition member is configured to be able to enter the interior of the housing 11. The transition member can insulate the distillation member 21 and the collector 22 to prevent heat transfer from the distillation member 21 to the collector 22.

[0077] In some embodiments, the auxiliary heating element 14 is used to heat the transition element so that the target component condensed in the transition element can melt and flow into the collection element 22 under gravity. By providing the auxiliary heating element 14 to heat the lower part of the housing 11, the target component condensed on the inner wall of the housing 11 and the support can be liquefied and flow into the collection element 22, thereby improving the collection efficiency.

[0078] In some embodiments, the transition member may include a heat insulation member 23. The heat insulation member 23 is spliced ​​between the distillation member 21 and the collection member 22 to insulate the distillation member 21 and the collection member 22 from heat transfer to the collection member 22.

[0079] In some embodiments, the distillation element 21 is disposed on the upper part of the housing 11, and the main heating element 13 is disposed facing the upper part of the housing 11, so that the distillation element 21 is heated by the main heating element 13, while avoiding excessive temperature at the lower part of the housing 11.

[0080] In some embodiments, a distillation positioning portion 211 is formed at the bottom of the distillation member 21, and a first heat insulation positioning portion 231 is formed at the top of the heat insulation member 23. The distillation member 21 and the heat insulation member 23 are spliced ​​together by the cooperation of the distillation positioning portion 211 and the first heat insulation positioning portion 231, which helps to maintain the stability of the distillation member 21 and the heat insulation member 23 after splicing.

[0081] See Figure 5 The distillation positioning part 211 and the first heat insulation positioning part 231 may have stepped surfaces, and the distillation part 21 and the heat insulation part 23 can be spliced ​​by the cooperation of the two stepped surfaces.

[0082] In some embodiments, the materials of the heat insulation component 23 and the distillation component 21 can both be graphite. Graphite has excellent heat insulation and high temperature resistance properties. At the same time, graphite can also avoid contaminating the materials.

[0083] In some embodiments, the transition member is disposed in the lower middle part of the housing 11, and the auxiliary heating member 14 is disposed facing the middle part of the housing 11. It is easy to understand that the upper part of the housing 11 has a higher temperature because the target component needs to be evaporated, while the lower part of the housing 11 has a lower temperature because the target component needs to be condensed. Therefore, the target component easily condenses in the middle part of the housing 11 and the area surrounding the middle part of the housing 11. In such an embodiment, the residue and accumulation of the target component in the easily condensable area outside the collecting member 22 can be effectively avoided, thus improving the recovery rate of the target component.

[0084] In some embodiments, the transition member may also include a condensation auxiliary member 24, which is spliced ​​between the heat insulation member 23 and the collection member 22. The vapor entering the housing 11 from the distillation member 21 can be condensed into liquid on the surface of the condensation auxiliary member 24 and flow into the collection member 22 under the action of gravity, thereby facilitating vapor condensation and collection by the collection member 22.

[0085] In some embodiments, the top of the condensation aid 24 and the bottom of the heat insulation member 23 can face the auxiliary heating member 14, which is more conducive to the target components condensed at the bottom of the heat insulation member 23 and the condensation aid 24 melting and flowing into the collection member 22 under gravity.

[0086] In some embodiments, the condensation auxiliary component 24 may include a perforated pipe 241. It is readily understood that if the structure were not perforated, steam material might condense on the condensation auxiliary component 24, which would hinder material recovery. By making the condensation auxiliary component 24 perforated, it is possible to condense steam, prevent liquid from condensing on the condensation auxiliary component 24, and facilitate steam diffusion and condensation. Furthermore, it allows the condensed liquid material to flow into the collection component 22 under gravity, preventing the liquid material from condensing on the inner wall of the condensation auxiliary component 24.

[0087] In some embodiments, the pipe fitting 241 is provided with a plurality of through-hole groups, which are spaced apart along the length of the pipe fitting 241. Each through-hole group includes a plurality of first through holes 2411 spaced apart along the circumferential direction of the pipe fitting 241. This arrangement can effectively promote uniform diffusion and rapid condensation of steam, while preventing liquid materials from solidifying on the inner wall of the condensation aid 24, thereby improving condensation efficiency and material recovery rate.

[0088] In some embodiments, the length of the first through hole 2411 along the length direction of the pipe fitting 241 is greater than the length of the first through hole 2411 along the circumferential direction of the pipe fitting 241, thereby helping the steam to diffuse and circulate better inside the pipe fitting 241, while ensuring that the steam can fully contact the inner wall of the condensation auxiliary component 24, promoting the rapid condensation of the steam into liquid, improving the condensation efficiency and the uniformity of material recovery.

[0089] In some embodiments, the condensation auxiliary component 24 further includes a plurality of reinforcing members 242 disposed radially inside the pipe component 241 and located between two adjacent through-hole groups. Since the condensation auxiliary component 24 needs to support the heat insulation component 23 and the distillation component 21, the perforated structure has an adverse effect on its mechanical strength. Therefore, this embodiment strengthens the structural strength of the condensation auxiliary component 24 by providing reinforcing members 242.

[0090] In some embodiments, the reinforcing member 242 is a plate with multiple second through holes 2422, which can ensure the structural strength of the condensing auxiliary member 24 while ensuring the flow of steam, which is conducive to the uniform diffusion of steam and contact with the surface of the condensing auxiliary member 24, thereby improving the condensing efficiency.

[0091] In some embodiments, the plate is connected to the lower edge of the first through hole 2411 in the upper through hole group of two adjacent through hole groups. This direct connection between the plate and the upper through hole group enhances the overall structural strength of the condensation aid 24 while maintaining the continuity of steam flow, ensuring that steam can pass through multiple through hole groups for condensation, thereby improving condensation efficiency.

[0092] In some embodiments, a second heat insulation positioning part 232 is formed at the bottom of the heat insulation member 23. The shape of the second heat insulation positioning part 232 is adapted to the top of the condensation auxiliary member 24. The heat insulation member 23 and the condensation auxiliary member 24 are spliced ​​together by the cooperation of the second heat insulation positioning part 232 and the top of the condensation auxiliary member 24, which is beneficial to maintaining the stability of the heat insulation member 23 and the condensation auxiliary member 24 after splicing.

[0093] In some embodiments, the second heat-insulating positioning portion 232 forms a stepped surface adapted to the top shape of the condensation auxiliary member 24, and the upper end of the condensation auxiliary member 24 is embedded in the stepped surface.

[0094] See Figure 5In some embodiments, the furnace body assembly 10 may further include a seal 112. An opening is formed at the bottom of the housing 11, and the housing 11 may include a housing connection portion 111 located radially outward of the opening. The seal 112 is disposed at the housing connection portion 111. The collecting member 22 may include a collecting body 221 and a collecting connection portion 222. A receiving groove 2210 for collecting the target component is formed on the inner side of the collecting body 221. The collecting connection portion 222 is connected to the top end of the collecting body 221 and is used for detachable connection with the housing connection portion 111 to seal the opening of the housing 11 using the seal 112. This arrangement simplifies the overall structure while ensuring a tight seal between the housing 11 and the collecting member 22.

[0095] In some embodiments, a heat dissipation structure 223 is formed on the outer side of the collecting body 221. The heat dissipation structure 223 cools the collecting component 22 by natural heat dissipation, thereby improving the cooling effect.

[0096] In some embodiments, the heat dissipation structure 223 may be a plurality of heat dissipation fins formed on the radially outer surface of the collection body 221.

[0097] In some embodiments, an annular groove is formed on the lower surface of the housing connection portion 111, and the seal 112 is disposed in the annular groove, thereby improving the fit between the seal 112 and the housing connection portion 111.

[0098] In some embodiments, the width of the annular groove opening is smaller than the width of the groove bottom, thereby preventing the seal 112 from detaching from the housing connection portion 111 and improving the stability of the seal 112 within the annular groove. In some embodiments, the cross-section of the annular groove can be trapezoidal to prevent the seal 112 from detaching from the annular groove.

[0099] In some embodiments, the furnace body assembly 10 may further include a sealing cooling element 113 for cooling the sealing element 112, preventing the temperature at the sealing element 112 from rising, and thus improving the sealing performance of the sealing element 112.

[0100] In some embodiments, the sealing cooling member 113 may include a cooling cavity formed in the housing connection portion 111. The cooling cavity is used for the flow of a cooling medium, thereby effectively reducing the temperature of the sealing member 112 and improving the sealing performance of the sealing member 112. The cooling medium in the cooling cavity can reduce the temperature of the housing connection portion 111, thereby reducing the temperature of the lower end of the housing 11, which is beneficial for condensation.

[0101] In some embodiments, the collecting member 22 may include a plurality of support portions 226 for supporting the condensation auxiliary member 24.

[0102] The support portion 226 is disposed radially inside the collecting body 221. The support portion 226 forms a stepped surface that matches the lower end of the condensation auxiliary component 24, so that the condensation auxiliary component 24 can be spliced ​​to the collecting component 22. When the housing 11 is connected to the collecting component 22, the support portion 226 can partially enter the interior of the housing 11.

[0103] In some embodiments, the distillation separation apparatus may further include a clamping assembly 30. The clamping assembly 30 is used to clamp the collecting connection 222 and the housing connection 111 to ensure a stable connection and sealing between the collecting member 22 and the housing 11.

[0104] In some embodiments, the clamping assembly 30 may include two clamping members 31 and two clamping drives 32 disposed opposite to each other. Each clamping member 31 forms a clamping groove 311. The two clamping drives 32 are respectively connected to the two clamping members 31 and are used to drive the two clamping members 31 to move relative to or away from each other, so that the collecting connection portion 222 and the housing connection portion 111 can enter into the clamping groove 311 and be clamped or removed from the clamping groove 311, thereby enabling quick disassembly and improving assembly and disassembly efficiency, making it more suitable for use in hot chambers.

[0105] In some embodiments, the clamping drive 32 may be cylinder-driven to facilitate assembly and disassembly.

[0106] See Figure 5 , Figure 5 yes Figure 4 The diagram shows a partially enlarged view of region A in the main structure of the distillation separation apparatus. In some embodiments, the collecting connection 222 forms a guide surface 2220, and the housing connection 111 forms a guide surface 1110, so that the collecting connection 222 and the housing connection 111 of the clamping assembly 30 can smoothly enter the clamping groove 311. The groove wall of the clamping groove 311 conforms to the corresponding surfaces of the collecting connection 222 and the housing connection 111 to ensure a stable connection and sealing between the collecting component 22 and the housing 11.

[0107] In some embodiments, both the guide surface 2220 and the guide surface 1110 are formed into conical surfaces; the wall of the clamping groove 311 is also formed into a conical surface. This arrangement can improve the clamping effect of the clamping assembly 30 on the connecting part of the collecting member 22 and the connecting part of the housing 111, which is beneficial to maintaining the sealing of the distillation separation device. At the same time, the conical surface also has a guiding function, which makes it easier for the collecting connecting part 222 and the connecting part of the housing 111 to enter the clamping groove 311.

[0108] In some embodiments, the distillation separation apparatus may further include a support platform 40. The support platform 40 may include a platform body 41 and a platform support member 42 connected to the platform body 41 for supporting the platform body 40. The furnace assembly 10 can be hoisted onto the platform body 41 for support and can also be hoisted away from the platform body 41. The platform body 41 is provided with a platform clearance channel 411. When the furnace assembly 10 is hoisted onto the platform body 41 for support, the housing connection portion 111 can extend downwards through the platform clearance channel 411 to below the platform body 41 to facilitate connection with the collection connection portion 222 of the collection member 22. This arrangement does not affect the overall hoisting of the housing 11 and the additional furnace section 122, facilitating the assembly and disassembly of the furnace assembly 10.

[0109] In some embodiments, the support platform 40 may further include a platform mounting plate 43. The platform mounting plate 43 is connected to the platform support member 42 below the platform body 41. The clamping assembly 30 is mounted on the platform mounting plate 43 between the platform mounting plate 43 and the platform body 41. The platform mounting plate 43 forms a mounting clearance through hole 431. The collecting connection portion 222 of the collecting member 22 can enter the clearance through hole and connect with the housing connection portion 111 of the housing 11. By providing the platform mounting plate 43, it is convenient to install the clamping assembly 30 on the support platform 40 and to hoist it together with the support platform 40.

[0110] In some embodiments, the distillation separation apparatus may further include a lifting mechanism 50. The lifting mechanism 50 is disposed below the platform body 41 on the support platform 40 and is used to lift the collection member 22, enabling the collection member 22 to connect to or separate from the housing 11. This facilitates the separation of the distillation collection member 20 from the housing 11, allowing the material to be separated to be placed into the distillation member 21, or the separated target product to be removed from the collection member 22, and the residual product after distillation to be removed from the distillation member 21. Furthermore, since the lifting mechanism 50 is disposed on the support platform 40, the lifting mechanism 50 can be hoisted together with the support platform 40.

[0111] In some embodiments, the support platform 40 may further include a platform base plate 44. The platform base plate 44 is connected to the lower end of the platform support member 42. The lifting mechanism 50 may include a plurality of guide members 51, a movable platform 52, and a lifting drive member 53. The two ends of the plurality of guide members 51 are respectively connected to the platform mounting plate 43 and the platform base plate 44. The movable platform 52 is movably disposed on the plurality of guide members 51, and the collecting member 22 is supported by the movable platform 52. The lifting drive member 53 is disposed on the platform base plate 44 and is used to drive the movable platform 52 to move up and down along the plurality of guide members 51. When the lifting drive member 53 or the clamping drive member 32 is damaged, the support platform 40 can be lifted off as a whole for repair or replacement.

[0112] In some embodiments, the mobile platform 52 is provided with a movable positioning groove 521. The collecting component 22 may include a first collecting positioning part 224 and a second collecting positioning part 225. The first collecting positioning part 224 and the second collecting positioning part 225 are connected to the bottom of the collecting body 221. The first collecting positioning part 224 enters the movable positioning groove 521 and cooperates with the movable positioning groove 521, and the second collecting positioning part 225 cooperates with the surface of the mobile platform 52. In the embodiments of this application, the first collecting positioning part 224 can position the collecting component 22, and the second collecting positioning part 225 can prevent the collecting component 22 from tilting, facilitating the assembly and disassembly of the collecting component 22 from the mobile platform 52. In such embodiments, the mobile platform 52 only provides support for the collecting component 22, and there is no substantial connection between the two.

[0113] When the lifting drive 53 drives the moving platform 52 upward to move the distillation collection component 20 to a preset position, the clamping drive 32 drives the clamping component 31 to move towards the housing connection portion 111, thereby clamping the collection connection portion 222 and the housing connection portion 111. Since the moving platform 52 only provides support for the collection component 22 and there is no substantial connection between them, when the lifting drive 53 drives the moving platform 52 upward, it is not necessary for the collection connection portion 222 and the housing connection portion 111 to come into contact; a gap of several millimeters can exist between them. When the collection connection portion 222 and the housing connection portion 111 are clamped by the clamping assembly 30, the collection connection portion 222 can move upward by several millimeters. In such an embodiment, when the lifting drive 53 drives the moving platform 52 to move upward, there is no need for the collecting connection 222 and the housing connection 111 to come into contact. At the same time, when the collecting connection 222 and the housing connection 111 are clamped by the clamping assembly 30, the moving platform 52 will not move upward, thereby avoiding adverse effects on the lifting drive 53.

[0114] In some embodiments, the depth of the movable positioning groove 521 is greater than 1 cm to prevent the collection connection 222 from completely disengaging from the support platform 40 due to the collection connection 222 shifting upward by a few millimeters when the collection connection 222 and the housing connection 111 are clamped by the clamping assembly 30. This also prevents the collection member 22 from being unable to enter the movable positioning groove 521 due to tilting or shaking when the clamping assembly 30 releases the collection connection 222 and the housing connection 111.

[0115] See Figure 6 , Figure 6This is a cross-sectional schematic diagram of a furnace body assembly according to one embodiment of this application. In some embodiments, the furnace body assembly 10 may further include a shell cooling member 15. The shell cooling member 15 is connected to the auxiliary furnace body section 122 below the auxiliary furnace body section 122, and is used to cool the shell 11 to condense the evaporated target component. This arrangement helps to shorten the length of the shell 11, allowing the evaporated target component to condense more quickly, thereby improving the condensation effect. The shell cooling member 15 can be lifted off together with the auxiliary furnace body section 122.

[0116] The embodiments of this application avoid the problem of low steam recovery rate due to high temperature at the bottom of the shell 11 by setting the shell cooling component 15; the shell cooling component 15 can make the temperature distribution inside the shell 11 reasonable, thereby improving the steam recovery rate.

[0117] In some embodiments, when the furnace body assembly 10 is hoisted to the platform body 41 and supported by the platform body 41, the housing cooling member 15 contacts the platform body 41. The housing cooling member 15 can also cool the platform body 41, thereby preventing the clamping assembly 30 from getting too hot and helping to reduce the temperature of the portion of the housing 11 located between the housing cooling member 15 and the sealing cooling member 113.

[0118] In some embodiments, see Figure 1 The platform body 41 is provided with a second positioning member 105 for positioning the housing cooling member 15 so that the housing connection part 111 is aligned with the platform clearance channel 411, so that the housing connection part 111 can extend downward to the bottom of the platform body 41 via the platform clearance channel 411.

[0119] In some embodiments, the middle part of the condensation auxiliary member 24 can face the housing cooling member 15, which helps to shorten the length of the housing 11 and improve the condensation effect.

[0120] See Figure 6 and Figure 7 , Figure 7This is a schematic diagram of a housing cooling component according to an embodiment of this application, omitting an annular plate. In some embodiments, the housing cooling component 15 may include an annular body 151 and a fluid separator 152 disposed within the annular body 151. The annular body 151 forms an annular cooling cavity for containing a cooling medium and an inlet and an outlet for the cooling medium to enter and exit the annular cooling cavity. The fluid separator 152 divides the annular cooling cavity into multiple fan-shaped cavities. The cooling medium entering the annular cooling cavity through the inlet can flow sequentially through each fan-shaped cavity and then flow out from the outlet. Through the multiple fan-shaped cavities formed by the fluid separator 152 within the annular cooling cavity, the cooling medium can be more evenly distributed around the housing 11, resulting in more uniform cooling. At the same time, the sequential flow of the cooling medium through each fan-shaped cavity prolongs its residence time within the annular cooling cavity, which is beneficial for more fully absorbing and carrying away the heat from the housing 11, thus achieving effective cooling of the housing 11.

[0121] In some embodiments, the annular body 151 may include an inner ring 1511 located radially inward, an outer ring 1512 located radially outward, and two opposing annular plates 1513 connecting the inner ring 1511 and the outer ring 1512. The inner ring 1511, the outer ring 1512, and the two annular plates 1513 together form an annular cooling cavity. The fluid separator 152 includes a plurality of radially distributed separator rods, each separator rod connecting the inner ring 1511, the outer ring 1512, and the two annular plates 1513, with a fan-shaped cavity formed between adjacent separator rods. In this embodiment, the cooling medium can more fully contact the housing 11 when flowing through it, increasing the heat exchange area and thus enhancing the cooling effect. At the same time, the radial distribution of the separator rods makes the cooling medium more uniform during flow, resulting in a more uniform cooling effect.

[0122] In some embodiments, the fluid separator 152 may include a first separator rod 1521. The two sector-shaped cavities formed by the first separator rod 1521 are not interconnected. The inlet and outlet are respectively connected to the two sector-shaped cavities formed by the first separator rod 1521, so that the cooling medium entering the annular cooling chamber from the inlet can flow through each sector-shaped cavity and then flow out from the outlet, thereby helping to ensure the cooling effect of the cooling component.

[0123] In some embodiments, the fluid separator 152 may further include a plurality of second separator rods 1522. The second separator rods 1522 are provided with at least one channel for the flow of cooling medium, and the two fan-shaped cavities formed by the second separator rods 1522 are fluidly connected through the channel so that the cooling medium can flow through the fan-shaped cavities, thereby ensuring the cooling effect of the cooling element.

[0124] In some embodiments, in two adjacent second dividing rods 1522, the channel of one second dividing rod 1522 is disposed near the inner ring 1511, and the channel of the other second dividing rod 1522 is disposed near the outer ring 1512, so that the cooling medium can cool different parts of the housing 11 more fully during the flow process, thereby improving the uniformity of the cooling effect.

[0125] In some embodiments, the two surfaces facing the second separating rod 1522 are respectively formed with a plurality of first grooves 15221 and a plurality of second grooves 15222. The first grooves 15221 and the second grooves 15222 face the two surfaces facing the two annular plates 1513 respectively. The first grooves 15221 and the second grooves 15222 form a channel with the two annular plates 1513, which is more conducive to the uniform temperature of the cooling medium in the fan-shaped cavity.

[0126] In some embodiments, the first groove 15221 and the second groove 15222 are spaced apart, which helps to make the temperature of the cooling medium more uniform in the fan-shaped cavity.

[0127] In some embodiments, the furnace body assembly 10 may further include a vacuum line 16. The vacuum line 16 is in fluid communication with the interior of the housing 11 to evacuate the interior of the housing 11.

[0128] In some embodiments, the vacuum line 16 is connected to the auxiliary furnace section 122 and to the housing 11 via the auxiliary furnace section 122, so that the vacuum line 16 can be used to evacuate the inside of the housing 11, thereby improving distillation efficiency and lowering the boiling point of the target component.

[0129] In some embodiments, the housing 11 is provided with a vacuum port, which is positioned facing the auxiliary furnace body section 122. A vacuum line 16 is connected to the vacuum port of the housing 11 via the auxiliary furnace body section 122. Since the housing 11 is connected to the auxiliary furnace body section 122, this arrangement does not affect the assembly and disassembly of the furnace assembly 10. Furthermore, because the vacuum port faces the auxiliary furnace body section 122, it facilitates the downward flow of steam along the housing 11.

[0130] In some embodiments, the vacuum port is located close to the housing cooling element 15, which facilitates vacuuming at the location where vapor liquefies, thereby reducing vapor loss.

[0131] In some embodiments, the vacuum line 16 passes through the second furnace outer shell 1221 and the second annular insulation member 1222 and connects to the vacuum port of the shell 11. Specifically, the vacuum line 16 may pass under the auxiliary heating member 14 and through the second annular insulation member 1222.

[0132] In some embodiments, the furnace assembly 10 may further include a temperature sensor 103 for measuring the temperature of the housing 11 to ensure that the distillation separation process is carried out at a suitable temperature.

[0133] In some embodiments, the furnace body assembly 10 may further include a temperature measuring pipe 114. The temperature measuring pipe 114 is fixedly connected to the housing 11 and extends vertically. The temperature measuring pipe 114 forms a bottom-sealed temperature measuring groove, into which the temperature measuring element 103 can be inserted. The furnace cover 1211 is provided with a channel for the temperature measuring pipe 114 to pass through, so that the temperature measuring pipe 114 can extend vertically to the top of the furnace cover 1211. This arrangement does not affect the overall hoisting of the furnace cover 1211 or the main furnace body section 121 and facilitates the installation of the temperature measuring element 103. At the same time, the bottom-sealed temperature measuring groove ensures that the installation of the temperature measuring element 103 will not affect the sealing of the housing 11.

[0134] In some embodiments, the lower end of the temperature measuring tube 114 enters the interior of the housing 11, making the temperature measurement results more accurate.

[0135] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0136] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
